 Abstract
Objectives: In this study, we investigated the biodegradation rates of 8 perfluorooctanesulfonate (PFOS) alternatives synthesized at the at Changwon National University in comparison to those of PFOS potassium salt and PFOS sodium salt. Methods: A biodegradability test was performed for 28 days with microorganisms cultured in the good laboratory practice laboratory at the Korea Environment Corporation following the OECD Guidelines for the testing of chemicals, Test No. 301 C Results: While , and were not degraded after 28 days, the 3 alternatives were biodegraded at the rates of 31.4% for , 25.6% for , 23.6% for , 20.9% for , 15.5% for , 8.5% for and 4.8% for . When the concentration was the same(500 mg/L), had the lowest tension with 20.94 mN/m, which was followed by (23.36 mN/m), (27.31 mN/m), (28.17 mN/m), (29.77 mN/m) and (33.89 mN/m). Having higher surface tension of 57.64 mN/m and 67.57 mN/m, respectively, than those of the two types of PFOS salts, and were found valueless as substitute for PFOS. Conclusion: The biodegradation test suggest that 6 compounds could be used as substitutes for PFOS. and were found to be the best substitutes based on biodegradation rate and surface tension, followed by , and . was found to have relatively low value as an alternative but it still had a potential to substitute the conventional PFOS.
